Consumer Unit move continued - a couple more questions

Jul 15, 2019 Last reply: 6 years ago 5 Replies

I'm still 'planning' the move of our consumer unit, I fear it's going to be a bit of a pig to do because the existing CU's wiring is rather inaccessible.



Be that as it may, I have a couple of further queries, I think I know the answers but I want to be quite sure:-



The new CU will simply have a main switch and all RCBO circuits, that's OK isn't it? We are TT and there is a 100mA time delayed RCD immediately after the company fuse in the garage. This feeds an 'outdoors' CU in the garage and, through a further fuse, the house CU via an underground cable.



I think I'll need to extend the incoming feed to the new house CU, what's the best way to do this. I guess a Henley Block is the obvious easy way, are there any alternatives? I could possibly solder and sleeve with heatshrink or I do have a hydraulic crimp tool so could get tube crimps and do it that way. Are there any special rules for incomers?


Any chance of pulling in new tails?

That sounds like the correct set up.

Not really, I think they're buried rather than in a duct and I know there's a joint half way, under ground.

Fair enough. I probably would crimp.
